5. P ress the “CLOCK” button again and the day display will flash. Use the “RH” buttons to change the value.
Use the “FAN” button to change the fan operation. There are 2 choices for fan operation: “ON” or “AUTO”. The factory preset is “AUTO”.
6. D on’t touch any buttons for several seconds until the display stops flashing, this will save your settings. If you need to change anything go back to step #1.
“ON” –The fan in the Ultra-Aire dehumidifier will run continuously. This does not affect either the dehumidification or ventilation functions of the system. The system may or may not be ventilating or dehumidifying while the fan is running. This setting is commonly used for maximum air filtration and/or air recirculation.
3.6 Adjusting the relative humidity “SETPOINT” The DEH 3000 senses the ambient relative humidity (%RH) of the space in which it is located, it comes factory preset to hold 50% relative humidity. The relative humidity “SETPOINT” (desired RH to be maintained) operates the dehumidifier function of the Ultra-Aire dehumidifier. It has no effect on the optional VENT (fresh air ventilation) or FAN (household air recirculation) functions if they are being used.
“AUTO” – Indicates the fan will run when the DEH 3000 calls for dehumidification or ventilation. If the control has not called for dehumidification for 3 hours, the control will automatically run the dehumidifier fan for 10 minutes. After a dehumidification cycle, the fan automatically shuts off for 10 minutes. This pause allows the water to drain from the dehumidifier.
Operation The standard range that the dehumidifier holds around your “SETPOINT” is 3%. With a setpoint of 50%, the dehumidifier will run until the relative humidity reaches 47%. The dehumidifier will then switch off until the relative humidity reaches 53%.
A solid “O” indicates the fan is operating. A flashing “O” indicates the fan is in a wait mode. No “O” indicates the fan is OFF. To set the operation: 1. P ress and hold the “FAN” button. The current fan setting will begin to flash on the display. Release the button. 2. P ress the “FAN” button to toggle between the “ON” and “AUTO” modes.
If the setpoint is higher than the ambient relative humidity, the space does not need to be dehumidified so the dehumidifier will not run. Example: Setpoint: 50% RH With the fan in the “AUTO” mode, the fan will operate only when needed by other functions of the system. The fan will remain OFF unless the system is dehumidifying or ventilating. The fan always runs during dehumidification and ventilation and the fan “O” icon will be lit. To completely turn the system OFF, use the “ON/OFF” button as described earlier.
Current condition: 45% RH –The dehumidifier will be off (no “O” indicator will be displayed). If your setpoint is below the ambient condition, the dehumidifier will be on and “O” will display. Example: Setpoint: 50% RH Current condition: 55% RH –The dehumidifier will be on (“O” displayed).

Installation, Operation & Service Manual
3.8 Damper Operation and Ventilation, Manual (Hold) Mode The “VENT” setting controls the ventilation function of the system. It has no control over the dehumidification function. In order to provide ventilation, the motorized damper must be open and the fan must be running. The controller takes care of these two functions automatically so that whenever the damper is open, the fan is running. The ventilation indicator “O” will be displayed whenever the unit is ventilating. The fan operation indicator “O” will also be lit.
The DEH 3000 will operate fresh air ventilation according to your ventilation program. The control needs to be programmed to turn the ventilation function ON and OFF at the desired intervals. This is done by programming the ventilation timer.
There are three damper operation modes: 1. “OPEN” – hold mode: The damper will be open and the dehumidifier fan will be continuously operating to introduce fresh air into the space. Use this mode for continuous fresh air ventilation. The fan is always on when the damper is open.
There are two programs available for ventilation: 1. Monday through Sunday
2. “CLOSED” – hold mode: The damper will never open, and the dehumidifier will not ventilate. The fan will still operate normally for recirculation and dehumidification.
2. Monday through Friday & Saturday/Sunday Each block of days has a morning schedule and a night schedule. Morning is the first 12 hours of the day and night is the second 12 hours.
3. “PROGRAMMED” mode: The DEH 3000 will operate the motorized damper and the dehumidifier fan according to the programmed ventilation schedule (Section 3.9).
Each schedule has:
The factory preset for the “VENT” setting is “CLOSED”.
• A “START” time when the ventilation schedule begins,
To set “OPEN” – hold or “CLOSED” – hold ventilation operation: 1. P ress the “VENT” button. The current setting will begin to flash on the display. Release the button.
• An “OPEN FOR” duration for the amount of time the damper stays open in 5 minute intervals, from 0 to 60,
2. P ress the “VENT” button again to switch between “OPEN” and “CLOSED”.
Setting the Ventilation Program: 1. P ress the “PROGRAM ENTER” button until the following menu appears:
• And “CLOSED FOR” duration which closes the damper for a specified time in 5 minute intervals from 0 to 60.
3. L eave the control alone for 10 seconds and your settings will be saved.

You can select from: “MON-FRI” “SAT-SUN” for separate weekday and weekend schedules, or “MON-SUN” which gives you equal weekday and weekend schedules. 3. Using the Up/Down “RH” buttons, highlight and then select one of the two choices. The example given shows how to program separate weekday and weekend schedules. The same method is used if you choose the other program.
Then press “PROGRAM ENTER” to select it. The display will appear as follows:
Example: menu when you select “MON-FRI” “SAT-SUN”:
1. E nter the starting time for weekdays using the up/down “RH” buttons to change the time. 2. P ress the “PROGRAM ENTER” button to switch to the “OPEN FOR” setting. Using the up/down “RH” buttons, change the duration that the damper will ventilate fresh air.
4.0 Temperature Cutout Programming Dehumidifiers produce heat when dehumidifying and depending upon outside conditions, the ventilation function may also introduce warm air. Some conditions may introduce enough heat to drive household temperatures up. The DEH 3000 temperature cutout feature disables all Ultra-Aire operations if household temperatures reach the cutout setpoint.
3. P ress the “PROGRAM ENTER” button to switch to the “CLOSED FOR” setting. Using the up/down “RH” buttons, change the duration that the damper will remain closed between ventilation cycles. For the example given, starting at 8:00AM in the morning, the control will ventilate fresh air for 15 minutes then stop for 15 minutes. This schedule of 15 minutes open, 15 minutes closed will continue until the start time of the night schedule.
In most installations this feature will not need to be used (the cutout is factory set to 99°F). If a lower temperature cutout is desired, program the setpoint by pressing and holding the “PROGRAM ENTER” button until the “PROGRAM” screen appears. Press the up/down “RH” buttons until “TEMP CUTOUT” highlighted. Then press the “PROGRAM ENTER” button again to select it. Now use the “RH” up or “RH” down buttons to adjust the setpoint. Press “PROGRAM ENTER” to return to the home screen.
Morning schedule is available anytime from 12:00AM until 11:59AM. Night schedule is available anytime from 12:00PM until 11:59PM. 4. Press “PROGRAM ENTER” again to go to the “MON-FRI” night schedule.
